To aZZ whom it may concern.

Be it known that I, LOUIS Anonmo. a citizen of the United States, residing at Kansas Gity, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Repeatin Attachments for Phonographs, of which the fol.- lowing is a full, clear, and exact description, such will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to a repeating attachment -lior sound reproducing machines anc seeks to provide a simple and effective repeating attachment which may readily be employed in connection with the usual disk record sound reproducing machine.

Sound reproducing machines are frequently employed for playing music for entertainments, advertising purposes and in the home, and motors that will drive the ma-' chine continuously are common, but when each record is played the position of the contacting parts of the machine must he repoint which requires the services of an attendant, so that. the machine will not play continuously without attcntion.

devices have heen devised that require building in the machine, but these cannot he readily attached to the usual form of machine after the latter is constructed. It is essential that an eilicient and inexpensive attachment be provided that may be attached to the machine that has been used so that any machine may easilybe converted to repeating machine, and so that the attachment may he removed when desired it being undesirable for a machine to always repeat.

lhe present invention. seeks to provide an improved repeating mechanism. for sound reproducing machines that readily be arranged on the usual disk record sound-reproducing machine and lifted from the ma chine almost instantly when it is desired to discontinue its use.

Vfith these and other objects in view, the invention consists in the features ofconstruction, combinations and arrangements of "parts hereinafter set forth, illustrated in the accompanying drawings and more particupointed out in the appended claims.

employing an attachment that is easily placed upon themachine and as easily re that by springing cl1ine illustrating the connection of the improved repeating attachment, the latter being shown in [plan vView.

Fig. 2, is a gmentary view in elevation of the *sound reproducing, machine, illustrating the connection. of the reproducing attachment thereto. I

F 3, is a fragmentary sectional view taken on line 1 1 of Fig. 1.

Fig. l, is a sectional View taken on line 1"-1"- of Fig. 1.

Fig. 5, is .a fragmentary plan viewoi the engaging and releasing lever of the mechanism.

The upper wall 8, disk record plate 5, arm 6, connecting tube 7 incasement 8 and needle 9 are of the common and well known construction employed in disk record sound reproducing machines, commonly called phonographs.

Resting on the wall. 3 at 10 and 3.1 is the bracket12 which spans the disk 4 and it is held in operative position by the springs 13, and 15, there being preferably no other means of securing the bracket to the plate.

Journaled in the bracket 12 at 16 and 17 is the shaft 18 the journal 17 being proton ably a pointed or cone shaped hearing so the bracket slightly the shaft is easily removed replaced in the position shown. The vertical. shaft 19 is journaled in the l'u'acket 12 at 20 and in the lever 21 at 22 and has rigidly mounted' thereon the frictional contact whcel23 and the worm pinion. 2 the latter meshing with the worln wheel 25, the lever being pivoted at 26, "l when the bracket 12 is properly loeatedg iie leverin position shown in full lines as Fig. 5 holds the wheel 23 in con-. tact with the disk 4-, while in the position indicated in dottcd lines of? Fig. 5 the lever holds the wheel out of engagement with the disk. When the wheel 23 is in engagement with the cisk 4 the shaft 18 will revolve by reason of frictional contact with the disk and the shaft 12 is rotated'through worm pinion 24 and the worm gear 525, this motion being continuous as long as the disk Patented-Inlay a, tort.

is revolved, many dislrs being driven by electric motors for continuous playin The shaft 18-is rovided with the slot 2-7 in which is mounted the binding screw 28 the letter securing the end 29 of the spiral spring shaped carrier 30, the carrier being otherwise freely mounted on the The carrier 30 is provided with the loop shaped projecting portion 31 in order to reach out from the shaft 12 and engage the hook 32 v which projects from the incasenient 8. lhis carrier is of a larger internal diameter than the diameterof the shall-1 18 end the loop; 31 is so shaped as tosp'ace the carrier around and away from the shaft so the the hook 352 will pass between the inner surface of the carrier and the lower side of the shaft as the hook traverses the carrier. Secured in the bracket 12 at 3B is the adjustable plunger shaped stop bar 3% which is hole in the desired position by the thumb set screw 35, the views representing a record plate .5 of a smaller dlonieter than the disk t which is the usual practice, it also being usual to employ record plates'ol? a diameter equal to the disk, the plunger 3 1+ being of sufficient range of adjustment to accommodate the employment of differentsize record plates, and being so adjusted as to contact with and stop the incasement 8 when the I needle 9 has been carried to the outer edge of the operative diameter of the record disk. The shaft 18 is sufiiciently elevated so I that when the incasement 8 reaches the position of full lines of Fig; 1 the projection 31 of the carrier 30 will engage the hook and hit the mcasement, lifting the needle 9 from the record plate 5, the hook continuing 1n engagement with the carrier and carryplunger shaped stop bar 3% can be :30 ad-- justed as to stop the incasement 8 at a posi' ion that will place the needle 9 at the be-' ginning of the record on the record plate.

lit is obvious that different lengthed carriers 30 are provided to serve the diilerent diameter of record plates and that the rier can he made of an accurate length to vsuit the dihnieter of the record plate'so resili htjj of the carrier will not be essential v ,ntageous. it is preferred however to employ a resilient carrierof a length that Will slightly contract when the incasemcnt 8 engages with the stop bar 8 1, thus avoiding accuracy of length in the carrier and allow chine for entertainments, advertising purrecord plate.

he improved repeating attachment'may easily be placed in position on the usual disk record sound reproducing machine and. removed therefrom at will, and it affords an effective and inexpensivecmeans of temporarily or permanently converting the usual phonog'aph to a continuous playing ms l poses and the like, 7
